To @ZZ whom it may concern:

Be it known that I, ARTHUR I. JACOBS, a

citizen of the United States, residing at Hartford, in the county ofHartford and` State of The object of the invention is to provide asimple, durable, and inexpensive machine of this class into which theblanks can be easily .fed and quickly and accurately presented to 4theaction of the moving cutting-tools, Whereby the blanks are formed veryrapidly into completed nipples, such as are employed for connecting thehubs and Wire spokes of wheels` of the kind designed for bicycles andother light vehicles.

The machine shown as embodying the several features of the invention isconstructed to receive headed blanks and successively present theseblanks to a tool which slots the headed end, to tools which bore outboth ends, to tools which slab off diarnetrically opposite sides of thesmaller end, to a tool which completes the perforation through theblank,-

to tools which slab off other sides of the smaller end, to a tool whichtaps the interior with a thread, and then to a tool which ejects thefinished nipple from the blank-carrier, as more particularly hereinafterdescribed, and pointed out in the claims.

Referring to the accompanying drawings, which illustrate a machineembodying the features of the invention, Figure 1 is a front elevationof the machine. Fig. 2 is a rear elevation. Fig. 3 is an elevation ofthe left end. Fig. f1 is an elevation of the right end. Fig. 5 is aplan. Fig. 6 is a View of the face of one of the movable tool-holdingcarriages. Fig. 7 is a view of the face of the other of the carriages.Fig. 8 is a face view of the blankcarrier. Fig. 9 is a face view of theplate that keeps theblanks from rotating in their holding-perforationsin the carrier. Fig. 10 is an edge view of the same. Fig. 11 is asectional view of the clutch parts employed for driving the tap-shaft;and Fig. 12 shows an enlarged side view of the blank, a side View of thenished nipple, and a sectional view of the nipple.

In the views, 1 indicates the bed of the machine, Which may be mountedon any desired form of legs. Supported in bearings held by a bracket 2,secured to the bed, is a shaft bearing a pinion 3 and a driving-pulley4, that may be belted to any convenient source of power. Extendinglongitudinally of the bed and supported by bearings attached thereto isa shaft 5, which, near each end of the bed, bears cams 6. This shaftalso bears a gear 7, that meshes with a pinion 3, so that When thepulley I is driven the cams 6 are rotated, Figs. 2, 3, and 5.

Secured to the upper face of the bed is a block S' with a bearing-sleeve9. This sleeve holds a journal that upon one end bears a star-Wheel 10,the notches of Which are adapted to be engaged by a'roll 11 on a pinprojecting from the face of the gear 7, and. upon the opposite end thejournal bears a disk 12, that is provided with a number of perforations13, which are adapted to receiveand hold the blanks While they are beingpresented to and acted upon by the operating-tools. The engagement ofthe roll with the starwheel causes the disk to advance one step at eachrotation of the gear, and as there are preferably eight notches in thestar-wheel there are eight successive intermittent steps during onerotation of the disk, Which, therefore, is preferably provided witheight blankholding perforations to correspond, Figs. 1,

2, and 11.

ports a bracket 19,in bearin gs secu red to which IOO is a spindle thathas on one end a driving-pulley 2() and on the other end a saw orsimilar slotting-tool 21. Connected with the bracket 19 is an arm 22,that supports a bearing in which there is a shaft that has on its endspulleys 23, and the belt for rotating the saw is passed around thesepulleys, Figs. 1, 2, and 7.l

Secured to the standard 1S is a bearing 24, in which is supported aspindle that hasa driving-pulley 25 at one end and a chuck 26, adaptedto receive a drill or similar boringtool, at the other end. This pulleyis belted to any convenient source of power for rotating the drill,Figs. 1, 2, and 7. To the same standard is secured a rod 27, whichprojects outward through a guiding-sleeve 28,attached A to the block S.rllhis rod is adapted to register with the perforations 29 in theblank-carrier disk 12, Figs. 1, 7, and 8.

When the carriage 14 is moved toward the blank-carrier disk by theengagement of the cam on the main shaft with the roll on the carriage,the rod 27'is advanced into one of the perforations 29, so as toregister and lock the disk in position, while the further forwardmovement of this carriage carries the saw and the drill mentioned closeto the disk, so that these tools will operate upon the blanks held inthe perforations in the carrying-disk in front of them.

A spring 30 is preferably secured to the bracket 19 so that its free endwill project into the vicinity of the edge of the saw and engage andhold the heads of the blanks While the saw is slotting them, Figs. 1, 2,and 7.

Projecting upward from the carriage 15 is a standard 3l. In bearingssecured near the top of this standard is supported a spindle that has onone end a driving-pulley 32 and on the opposite end a chuck 33, that isadapted to hold a drill or similar boring-tool. The axis of this drillis preferably located in line with the axis of the drill borne by theother carriage, so that both drills may operate upon opposite ends ofthe same blank simultaneously, Figs. 1, 2, 5, and 6. Secured to thisstandard 31 is a bracket 34, in bearings in which is held a spindle thathas on one end a pulley 35 and on the other end a pair of mills orsimilar cutting or abrading tools 36. Secured to the same standard is abracket 37, having a bearing in which is a spindle that has a pulley 33and another pair of mills or similar abrading or cutting tools 39, Figs.l, 5, ando. These mills are located with relation to the axis of theblank-carrying disk just ninety degrees apart, so that the first rsetoperate to slab off two diametrically opposite sides of the end of theblank presented to them, and then when the saine blank is carried aroundninety degrees the other set operate to slab off the other diametricallyopposite sides and thus square that end of the blank.

To keep the blanks from rotating in the holdin g-perforations and insurethat they are correctly presented to the mills, so the slabbing willaccurately square the ends, a plate 40 is secured to the block 8, and onthis is formed a rib 41, that projects outward on the arc of a circleinto the path of the slots that are sawed in the heads of the blanks.When the blanks are carried around the ninety degrees from one set tothe other of the slabbilig-mills, the slots travel along this rib, sothat the blanks will be turned just the ninety degrees and be presentedso that the mill cuts Will be at right angles with each other, Figs. 1,6, 9, and 10.

Supported in bearings 42, secured to the standard 31, is a spindle thathas on one end a pulley 43 and on the opposite end a chuck 44, adaptedto hold adrill or similar boringtool, Figs. 2 and 6.

A bea-ring sleeve 45, that is preferably formed in two sections joinedtogether by a yoke, is supported by the standard 31. In one of thesections of this sleeve is a shaft with a pulley 46 and a clutch part47, and in the other of the sections is a shaft that has a pulley 48 anda clutch part 49. These pulleys 46 and 4S are belted so as to be rotatedin opposite directions. A spindle is passed through a perforation in oneof the shafts, and on one end this spindle has a clutch part 50, and onthe other end is a clutch 5l, that is adapted to hold a tap or similarthreadingtool. The clutch part on the spindle is complementary to and isadapted to be engaged with either of the clutch parts connected with theshafts. into the blank against the material, the spindle is pushed backso that its clutch part engages With one of the shaft clutch parts andis consequently rotated in one direction, but When the tap is beingpulled back out of the blank by the backward movement of the carriagethe pull of the threads in the material will draw the tap and spindleforward so that its clutch part disengages from the clutch part thatdrove it in and becomes engaged with the other of the shaft clutch partsand thus is rotated in the reverse direction. By means of this the blankcan be readily tapped by the forward feed of thecarriage and the tapunscrewed when the carriage moves backward Without any complicatedmechanism or fine adjustment of the parts, Figs. 1, 5, and 11.

A rod 52 is held by the standard 31 with an end projecting toward theblank-carrying disk in such manner that when the carriage 15 movestoward the disk the end of the rod will push the finished nipple fromthe perforation opposite it, and when this carriage moves toward thedisk both of the sets of mills and both of the drills and the tap whichit carries, as well as the ejecting-rod,are brought up to accomplish thework on the ends of the blanks, Figs. 1, 5, and 6.

In the machine illustrated the tools that operate upon both ends of theblanks are arranged in a circle forty-five degrees apart When the tap isbeing forced.

about the axis of the carrying-disk, and after the tools havesufficiently operated upon the ends of the blanks held in theperforations of the carrying-disk the cams reach a position whichpermits the spring to force the carriages with the tools back from theends of the blanks and Withdraw the locking-rod, so the disk may beadvanced another step. When the tools are again brought up to the endsof the blanks, they encounter those next in succession. blanks aftereach movement of the disk,

which of course presents the blanks differently. As all of theoperations on the blanks are carried on from both sides simultaneouslythe blanks are rapidly formed into completed nipples, and as fast as oneis finished and reaches a position opposite the ejector it is thrown outand another blank inserted in the cleared perforation. It is preferredthat the cams be so timed that the carriages are moved from each othermore rapidly than toward each other. Y

As the empty perforations in the disk of this machine come around blanksare inserted With their heads toward the right. A blank located in thismanner is first carried by the disk in front of the saw that slots itshead. It is then carried into line with the drills that boro it fromboth ends. The next movement of the disk carries this blank intoposition to be operated upon by the irst set of slabbingmills. Then itis carried to the drill that completes the perforation. Next it ispresented to the second set of slabbing-mills. Then it is presented infront of the tap for tapping, and nally it is ejected from the machine.As stated, when all of the perforations are filled With blanks theseoperations are carried on simultaneously from both sides on thesuccessive blanks, as all of the tools are brought up by the carriagesafter each movement of the carrying-disk. With this construction theblanks are automatically presented rapidly to the actions of thedifferent cutting-tools in such manner that they are operated upon quiteaccurately, and as a number of blanks are being operated uponsimultaneously in this manner a large quantity of iinished nipples canbe produced by this machine in a given period.

The construction of this machine is such that the mechanisms are notliable to get out of repair nor to Wear so as to operate inaccurately.When the mechanisms are set in motion, they operate to form the nipplesso long as the blanks are fed to them.
